As if a meal here isn’t decadent enough, Halloween’s desserts ask how good or bad you want to be. For the sinners, the Devil’s Pitchfork is a decadent chocolate cupcake filled with Godiva liqueur ganache while the saints enjoy Angel’s food cake flowing with sweet liqueur. And because it’s Vegas, they’ve tossed in a pair of edible fruit-leather panties for good measure. $12, Oct. 31 only, in the Cosmopolitan, 877-893-2003.
